Abstract

The invention relates to a motion absorber comprising a housing (1), a connecting member (2) that is mounted to be movable with respect to the housing and that is linked with a movable part whose motion should be absorbed, and an absorber element that absorbs the motion of the connecting member (2) in the housing (1). Conventional motion absorbers are disadvantageous in that their operability is limited at wide temperature variations. The aim of the invention is therefore to provide a motion absorber whose absorbing effect is as independent of the ambient temperature as possible. To this end, the absorber element is a two-part structure and comprises a permanent magnet (3) and an opposite pole (4). One part is arranged on the housing (1) and the other part is arranged on the connecting member. The magnetic force acting between the permanent magnet (3) and the antipole (4) absorbs the motion of the connecting member (2) in the housing (1).
